Application filed October 23, 1919. Serial No. 332,690.

To all whom it may concern: Y

- Be it known that JORDAN T. BRUMFIELD, late a citizen of the UnitedStates, residing at Portland, in the county of Multnomah and State ofOregon, has invented a new and useful Loose-Leaf Binder, of which thefollowing is a specification. I

His invention refers more particularly to that class or books in whichthe leaves are perforated and inserted in loose leaf form.

The object of his invention is to provide an exceedingly simple andeflicient means for holding perforated sheets in book form in quantitiesmuch greater than is possible with the present appliances, and to do soin much better form, and at the same time rendering the addition orremoval of any of the leaves a very simple operation.

He attained these results in the manner described in the followingspecification and illustrated in the accompanying drawing.

Referring to the drawing. Figure l is a plan of the binder portion ofthe device showing it in locked position; Fig. 2 is a front elevation ofFig. 1; Fig. 3 illustrates the device unlocked and the back moved out ofthe way preparatory to opening the binder; Fig. 4 is an end elevation ofFig. 3 showing the sheets in place and the binder open.

Similar letters and numbers of reference refer to the same or similarparts through out the several views.

Referring in detail to the drawing. A is a flexible back which issecured to the flexible cover A to which is secured a pocket A ifdesired. A are perforated sheets which this device is intended to unitein book form.

H is a base plate of thin metal which is secured by means of the rivetsH to one edge of the flexible inner back A This base plate H is U shapedand holds the edge of the back A between its members, the object being,of course, to furnish a flexible hinge for the base plate, this hingebeing supplied by the leather in the back A On the base plate H arepivotally mounted the two arms H whose pivots are termed by the lowerends oi the standards H. On the swinging end of the pivoted arm H ismounted the swinging standard H. The upper end of the pivoted standard His supplied with a slot H which is adapted to receive the tongue H onthe upper end of the swinging standard H and the upper ends of both ofthe standards being curved in a manner to form an approximatesemicirclewhen joined. The lower end of the swinging standard H is hinged to theswinging end of the pivoted arm H at the oint H It will be understoodthat the flexible inner back A is secured to the back of the binderwhich is integral with the cover A Only the edges of this flexible, backare loose and one side serves as a hinge for the base plate H and theother side serves as a hinge :tor the cover plate U.

L is a cover plate similar in size and mode of attachment to theflexible back as is the base plate H and is supplied with the slots Ladapted to receive a portion of the aforementioned semi-circle formed bythe upper ends of the standards H and H Hooks L are rotatably mounted onthe cover plate L in a manner that their tips may swing underneath therespective arches formed by the upper ends of the standards L and L asthey pass through the slots L The hook L is mounted on the pivot L*.

It will be observed in Figs. 1 and 2 that the arm H and its standards Hand H are set at an angle to the cover plate L corresponding to theangle of the slots L 'However, when desiring to add or remove leaves toor from this binder the pivoted arms H are moved into the position shownin Fig. 8, and the swinging standard H is swung back into the positionshown in Fig. 4, which of course opens the binder and permits thedesired mnipulation of the leaves.

lVhile l have thus illustrated and described his invention it was nothis intention to limit himself to this particular form or method ofapplication, but intended that it should cover all forms andmodifications that fall fairly within the appended claims.

What he claimed as new and desired to protect by Letters Patent of theUnited States, is:

1. A loose leaf binder consisting of a base plate mounted on a hingeinside of a book a manner to permit the tip of said hooks to passbetween said arches and said cover plate when moving away from saidcover plate hinge.

2. A loose leaf binder consisting of a cover member, a flexible backsecured to the inside of said cover member, a base plate secured to oneedge of said flexible back, a pair of swinging arms mounted on said baseplate at a distance equal to the distance between the perforations inthe sheets, a standard mounted on each of said arms and forming itspivot, said standard having a curved upper end whose tip is suppliedwith a slot, a swinging standard hinged to the swinging end of saidswinging arm, said swinging standard having a curved upper end'whose tipis supplied with a tongue adapted to fit into the slot in the tip ofsaid fixed standard, said standards when joined standing in a parallelposition and forming a semi-circle at their upper end, a cover platesecured to the edge of said flexible back member, said cover .platehaving slots adapted to receive thearch formed by said standards whenclosed and said slot having a total length somewhat less than the totalbreadth of said arch, hook members pivoted on said cover plate in amanner to permit the tip of each book to pass between said cover plateand the projecting portion of one of said arches.
